C#调用科大讯飞离线语音合成TTS
c#调用科大讯飞的离线语音合成，需要在科大讯飞开放平台:http://www.xfyun.cn 注册、创建应用(获取APPID)、开通离线语音服务、下载SDK。
SDK中目录如下:
关于目录结构，讯飞平台的资料库中有介绍。
bin目录下有msc.dll动态库。c#调用科大讯飞的语音合成，需要引用该文件。该文件是C语言生成的dll，C#没办法直接引用。所有需要用C#重新封装一个TTS.dll，然后再在C#项目中引用封装的TTS.dll。
步骤:
1.在VS中新建一个类库项目(TTS)，新建一个类文件(TTS.cs)
2.TTS.cs中的内容如下:

3.把该类库生成一个TTS.dll
4.在C#项目中引用该类库TTS.dll
5.另外需要把下载的SDK中的msc.dll放到语音合成项目中的Debug目录下面(可以百度一下C#调用C/C++的DLL)
